Interesting. Fors for me correctly. When I run it manually, I get this:
bash-5.0# devlink dev param show netdevsim/netdevsim11 name test1 -j | jq -e -r
'.[][][].values[] | select(.cmode == "driverinit").value'
true
bash-5.0# echo $?
0
bash-5.0# devlink dev param set netdevsim/netdevsim11 name test1 cmode
driverinit value false
bash-5.0# devlink dev param show netdevsim/netdevsim11 name test1 -j | jq -e -r
'.[][][].values[] | select(.cmode == "driverinit").value'
false
bash-5.0# echo $?
0

Not really, for non-existent param the return value would be wrong:
bash-5.0# devlink dev param show netdevsim/netdevsim11 name test2 -j | jq -e -r
'.[][][].values[] | select(.cmode == "driverinit").value'
devlink answers: Invalid argument
bash-5.0# echo $?
4
bash-5.0# devlink dev param show netdevsim/netdevsim11 name test2 -j | jq -r
'.[][][].values[] | select(.cmode == "driverinit").value'
devlink answers: Invalid argument
bash-5.0# echo $?
0
The return value is 0 like everyone is fine. You probably have a
different jq version (1.6). Looks like I need to use the same
workaround I have in tools/testing/selftests/net/forwarding/tc_common.sh.
I thought that -e would avoid that.
